CVE-2011-4858

Publication date 5 January 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Apache Tomcat before 5.5.35, 6.x before 6.0.35, and 7.x before 7.0.23 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.
